Outline
Taking a region in the Hangzhou Bay area of China as an example, this study refined the local anthropogenic emission inventory and incorporated it into the regional air quality model WRF-CMAQ. The source contributions to ozone pollution during a typical month were quantitatively analyzed using the Integrated Source Apportionment Method (ISAM) and the Integrated Reaction Rate (IRR) method within CMAQ. The results showed that ozone pollution in this area was mainly attributed to contributions from outside the region, accounting for 73.3%, while local contributions accounted for 26.7%. However, on pollution days, the local contribution was found to increase to 35.6%. Furthermore, the contributions of different local emission sectors were analyzed, and industrial and transportation emissions were identified as the major anthropogenic sources of local ozone formation, contributing 38.3% and 35.4%, respectively. Based on the source apportionment results and considering the region's actual control policies and reduction potential, a refined emission reduction strategy was designed for 40subcategories of anthropogenic sources. This strategy was implemented as an emission control scenario in the CMAQ model to assess its effectiveness. The results indicated that the refined reduction plan significantly reduced locally formed ozone on pollution days, with a maximum reduction of up to 26.44μg/m3 and an average reduction of 3.5μg/m3, representing 7.1% of the locally produced ozone concentration during the pollution period.
